Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Need help to build a RISC-V Processor on Artix-7 FPGA: Final Year Engineering Project Guide
With LiteX you can synthesize a VexRiscV processor. You can run Linux on it. The toolchain is pretty easy to use, as long as you use Xilinx Vivado to compile to gateware.

Sunset TCL scripts ?
LiteX is a great example of a Python-first flow. However, they have chosen not to subordinate the scripting environment to a GUI toolchain - EDA vendors are unlikely to choose the same trade.

Been messing around with litex and migen on my Tang Primer 20K
To lean these: https://github.com/enjoy-digital/litex, https://github.com/m-labs/migen
- CPU design for college project
- How can I learn about RISC-V and use case? I want to do a project for begginers

How Much Would It Cost For A Truly Open Source RISC-V SOC?
If you use LiteX to generate a VexRiscV system-on-a-chip, you can include an open source DDR DRAM PHY. This works on Xilinx Spartan-6, Spartan7Artix7/Kintex7/Virtex7 FPGAs, and Lattice ECP5 FPGAs. DDR/LPDDR/DDR2/DDR3 depending on the FPGA.

Using FPGAs for computations as a beginner
I am interested in trying out FPGAs for the purpose of running specific calculations more efficiently. Since the calculations themselves are quite complex, I would need to be able to program in a relatively high-level language. I've seen that designing SoC in Python is possible, for example with Litex (https://github.com/enjoy-digital/litex) or Amaranth (https://github.com/amaranth-lang/). I don't want to spend hundreds of hours learning about FPGAs, but I'm prepared to take on a challenge.

Designing a RISC-V CPU, Part 1: Learning hardware design as a software engineer
I've had this recommended and it looks v promising! https://vivonomicon.com/2020/04/14/learning-fpga-design-with...
Someone above has mentioned Robert Baruch too: https://github.com/RobertBaruch/nmigen-tutorial
I also found this helpful: http://blog.lambdaconcept.com/doku.php?id=nmigen:tutorial
And there is of course the IRC channel if you want to ask people questions, #nmigen on irc.freenode.net
